SHORE.

Application filed May 19, 1923. Serial No. 640,252.

T0 all whom t may concern.'

Be it known that I, OSCAR L. VALLAGE, a citizen of the United States,residing at Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented new and useful Improvements in Shores, ofwhich the following is a specification.

This invention relates to shores for use in building construction. Y

One of the main objects of the invention is to provide a shore which maybe readily adjusted and the parts of which may be quickly and easily buteffectually secured in adjusted relation. This invention is intendedmore particularly as an improvement and simplification of the shoredisclosed in my U. S. Patent,1,400,109, the primary object of thepresent invention being to simplify the shore disclosed ink my patentreferred to and to produce a shore which may be quickly and easilyadjusted whilebeing of very simple and eii'icient construction. vFurther objects will appear from the detailed description. g

In the drawings Figure l is a'front View of the lower-keeper andassociated parts;

Figure 2 is a section taken substantially on line 2 2 of Fig. 1; j

Figure 3 is a front view of the shore;

Figure 4 is a side view;

Figure 5 is a back view.

The shore includes an uprightl which is preferably formed of a suitablelength. of angle iron. A post 2 which may be formed from a suitablelength of three-by-four studding or timber is slidably mounted inupright 1. This post slides through a lower U-shaped keeper 3 and anupper U-shaped keeper 4. The lower keeper 3 is inclined dowlmf'ardly andforwardly of the shore and is pivoted on gudgeons 5 which project fromthe ends of a block 6 extending across the back of upright 1, nuts 7being threaded onto the gudgeons to prevent spreading apart of the armsof keeper 3. Block 6 is provided on its inner face with a stud 8 Vwhichis adapted to fit into any one, selectively, of a plurality of openings9 provided for this purpose through rear arm 1a of upright l. A wedge 10is driven between the bight portion of lower keeper 3 and the lowerportion of post 2 which has its lower end portion beveled to provide aninclined surface 2a. Upper keeper 4L is pivoted on a pin 1l which passesthrough a sleeve 12 of a plate 13 riveted at 14 on arm 1a of post l,nut-s 15 being threaded on the ends of pin ll, This upper keeper 4 isalso inclined downwardly and forwardly of upright 1 and a wedge 16 isdriven between the bight portion of keeper l and post 2. This providessimple and eiiicient means whereby the post is effectually secured inadjustment.

In using the shore, the lower end of post 1 is placed upon a suitablesupporting member or plate a after which a suitable jack A is supportedin position upon the upright with the head of thel jack in contact withthe lower end of post 2. The jack may be supported in any suitable orpreferred manner though I prefer to use a hook b which is secured to thejack and is adapted to engage through any one, selectively, of theopenings 9, as clearly illustrated and described in my patent aboveidentified. Post 2 is raised into position by means of jack A, afterwhich keeper 3 is adjusted and the wedges 10 and 16 are driven inposition. The block 6 and stud 8 effectually secure keeper 3 againstdownward movement while permitting this keeper to be readily adjustedwhen wedge 10 is removed or loosened during adjustment of post l2. Bythis means I provide a very simple and eii'icient device which may bequickly and easily adjusted and in which the post is effectually securedin adjusted position. lhile I have described and illustrated the use ofan angle iron for standard 1 I can, if desired, use a suitable piece oftimber, such as a three-by-four studding, which is provided in itsrearward face with recesses for reception of stud 8, post 2 beingslidably mounted and secured in adjustment by means of the keepers 3 and4 and asso ciated parts in the manner described.

What I claim is In a shore, an upright, a post slidably mounted on theupright, means at the upper end of the upright for preventing outwardmovement of the post away from the upright, a block extending across therearward face of the upright and provided with an inwardly projectingstud, the upright having a vertical series of openings for reception ofsaid stud whereby the block is adjustably mounted on Said upright andposiw tively secured in adjustment thereon, the lower' end portion ofthe post being beveled downwardly and inwardly of the upright, a keeperpivoted to the ends of the block and extending across and in front orthe beveled portion of the post, and a- Wedge driven between the bightportion of the keeper and the beveled portion of the post and ooactingVwith the keeper for eeeting upward adjustment of the post and forSecuring the post in adjustment. Y

In testimony whereof I my signature.

OSCAR L. WALLACE.
